WATER-CLOSET VALVE;

SPECIFICATION forming part of Letters Patent No. 638,594, dated December 5, 1899.

Application filed Julyl3, 1899. Serial No. 723,727. (No model.)

To a whom it may concern.-

Be it known that I, CHARLES PERKES, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and useful Improvement in VVater Closet Valves; and I do declare the following to a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the figures on the accompanying drawings, which form a part of this specification.

The object of my invention is to provide a water-closet or hopper valve with a wastepipe adapted to be shut ofi when the watercloset is in use and through which no leak or waste water will pass after it has drained the water off above the inlet or main valve to prevent freezing. As usually constructed, valves of this type generally open the wastepipe when the water-closet is in use, which cuts down the pressure and diminishes the flow of water, besides resulting in an enormous waste of water. In some municipalities ordinances have been passed prohibiting the use of all hopper-valves which allow any waste of water while the water-closet is in use, so great has this evil become. My invention remedies this defective construction in valves of this class, and the invention consists in the following combination of parts, the details of which will first be described and the features then set forth and claimed.

Figure 1 represents a central longitudinal section of a valve embodying my improvements. Fig. 2 is a transverse central section of the valve. Fig. 3 is a top plan view of the same.

1 represents the valve, having the inletpipe 2, the outlet-pipe 3, and waste-pipe 4c.

5 is the flanged bed-plate of the valve, into which the valve is screwed, and 6 is the usual spring surrounding the valve-stem, which normally seats the main valve.

7 is the valve-stem, having the main boxed valve 8, with its usual packing, adapted to seat against the main-valve seat 9-, formed in the valve.

10 is a conical valve carried above valve 8 and adapted to seat in the conical seat 11. The usual screw-cap 12 and packing closes the upper end of the valve, through which the valve-stem 7 projects.

The waste-pipe eterminates in an opening 13, formed in the lowermost portion of the valve-seat 11. The lower portion of said valve-seat 11 is cut away all around except in the immediate neighborhood of the wasteopening 13.

The diameter of the valve 10 is less than the valve-casing within which it works, so that no moisture or film of water can be entrapped between the sides of the valve and the casing, where it is liable to freeze in cold weather. When the main valve 8 is seated, the waste-port, being below the valve-seat 11, drains the said seat dry, so that both the valve 10 and the seat 11 are perfectly drained,

thereby preventing any clogging of the valve by freezing, which would render the valve inoperative.

In operation the spring 6 normally closes the outlet through the valve, and any water which remains in the outlet-pipe after the valve has been operated and the closet flushed drains out through opening 13 into wastepipe 4. The position of opening 13 is such that no water can remain in the conical valveseat 11, and the valve-seat and valve cannot, therefore, freeze, so as to be rendered inoperative. When the valve is opened ,by depressing the valve-stem, the valve 10 instantly seats and closes the waste-opening 13, so that no water can waste through the valve while the water-closet is occupied. When the pressure on the valve-stem is released, the valve 8 instantly seats and the valve 10 unseats and the water in the oatlet-pipe and in the lower portion of the valve all drains out through the waste-pipe to the level of said waste-pipe, which is below the waste-valve seat 11. The

waste valve 10 is thereby prevented from freezing by the accum ulation of water therein.
